Abstract: Case No.   1-750211VT          Applicant: Francis S. Szabo Title:     PHOTOCOMPOSITION MACHINE FONT SOURCE            ABSTRACT   A turret mounted series of photocomposing disc fonts wherein the turret has a series of disc hubs all having a different elevation in order that the disc members may be bunched together in overlapped relationship and hence occupy a minimum area within the photocomposing machine. The turret is rotated to select a particular disc for insertion into an optical system, and is advanced or retracted along its own axis according to the elevation of the particular hub selected in order that the optical system of a photocomposing machine may remain stationery, and the particular disc member be brought to the proper focus position within the optical system. The advance in the art is primarily in the placement of the discs in overlap relationship and then advancing or retracting the turret in order to accomplish proper positioning of the disc as opposed to the concept of the prior art in keeping all discs on one plane and then rotating the turret to bring each disc in turn into the optical system.

Abstract: CAM ACTUATED TREE CUTTING SHEARS     AND BUNCHER                     Alva Z. Albright, Inventor ABSTRACT        Shear knives are pivoted, side by side with sharp edges opposed, by a pair of adjacent ends to a pivot strap.  Cam rol-lers are respectively for rotation on the knives at the junc-tions of their free ends and outboard sides.  Rearwardly converg-ing cam edges are mounted in forwardly extending arms of a for-wardly movable frame, the arm being adapted to receive the pivot strap transversely therebetween and a tree of not over an equal diameter.  The knives are slidably mounted in slots in the respective arms with their free ends forward and their roller cam followers respectively engaging the converging cam edges on which they are spring biased forwardly.  The knives are cammed closed to cut a tree as the movable frame moves forwardly relative to tree and knives. A swinging member, hav-ing a transverse blade pivoted to the top thereof, is itself pivoted to one of the pair of arms and is hydraulically actu-ated to swing past a cut tree between the arms and back to raise the tree clear of the shear knives an onto a raised floor rearwardly and hold it there.  A second pair of arms vertically spaced above the first pair also receives the tree which is re-leasably retained therebetween by a one-way pair of gates at the ends thereof.

Abstract: ABSTRACT OF THE DISCLOSURE      Combines a storage protect key stack with an access key register (AKR) and active access key (AAK) select circuits.          Storage key entries in the stack correspond to the physical blocks in main memory.  This combination can provide storage protection for different storage access types within address sub-ranges in the main memory associated with respective access keys.  The sub-ranges are blocks of addresses within the full range of addresses of the physical memory.  The protect key operation applies to physical addresses, and it obtains system addressing compatibility with an address translation operation using the same access keys as address keys with program logical addresses.    Special features include a shared protect key, which need not be loaded in the AKR, to make specified sub-range(s) shareable by all users of the system, so that any user can access the blocks in memory associated with the shared protect key.  For I/O accesses, an override is provided which ignores any read-only control of any memory block to which an I/O access is requested.  Supervisor accesses can be made in all key areas, regardless of the AAK, the protect keys, or the read-only flag bits.

Abstract: MICROWAVE OVEN EXCITATION SYSTEM FOR PROMOTING UNIFORMITY OF ENERGY DISTRIBUTION     ABSTRACT OF THE DISCLOSURE         A microwave oven includes a relatively flat mode stirrer cavity mounted on the outside of one of the cooking cavity walls, sharing a common wall therewith.  Disposed within the mode stirrer cavity is a rotating fan-like mode stirrer.  A waveguide supplies 2450 MHz microwave energy to the mode stirrer cavity.  Two aperture elements of generally slot configuration and oriented at right angles to each other in the common wall couple energy from the mode stirrer cavity into the cooking cavity.  The configuration and relationship of the aperture elements promote uniformity of energy distri-bution and readily permit adjustment of the energy distribution by empirically adjusting the precise size and location of each aperture element.  In one embodiment of the invention, two aperture elements overlap to form a single aperture of sub-stantially cruciform configuration.

Abstract: ABSTRACT OF THE DISCLOSURE          A refractory lined metlting furnace particularly suited for separation of non-ferrous metals with embedded or attached ferrous components, includes a casing or body pivotally mounted and tiltable by means of fluid operators.          The interior is divided by a vertical wall into a combustible waste burning portion for the generation of combustible gases to assist in heating the furnace, and a melt chamber into which a variety of metallic waste can be charged for melting.          Conventionally fired burners are supplied to the melt cham-ber and to the combustible waste portion.  The temperature of the melt chamber is raised to the melting point of the metallic waste material having the lowest melting point, e.g. aluminum, and when the aluminum is melted, the furnace is tipped forwardly so that the aluminum runs through drainage apertures into a liquid metal holding chamber provided on the floor of the melt chamber.  When the molten metal has drained, the furnace is tilted rearwardly to discharge the remaining scrap out through charging doors at the rear of the melt chamber.  The sequence is repeated with heat being supplied from the combustible gases formed in the combusti-ble waste burning portion, until the storage chamber is full whereupon the furnace is tilted and the molten metal dis-charged from a tapping hole in the front of the storage cham-ber.  If metal such as copper is part of the residue of the combustible waste material, it may be heated to the molten state by the burner in this section and then poured through a further tapping hole communicating with this section.

Abstract: Abstract of the Disclosure A ball valve comprises a ball shaped closure mounted on spindles extending at right angles to a flow passage in the valve body.  Between the closure and the regulating spindle a parallelepiped-shaped joint portion is formed on the end of the regulating spindle to engage bearing blocks in the adjacent part of the closure on both sides of the joint portion of the regu-lating spindle.  The blocks are mounted to turn about axes parallel to the regulating spindle and have opposed planar surfaces.  The clearance between the joint portion of the regulating spindle and bearing blocks is greatest when the joint portion is parallel with the bore of the closure, and becomes smaller and finally disappears when the direction of the joint portion of the regulating spindle is made to deviate in relation to the closure bore in either direction of turning.  The joint between the regulating spindle and the closure thus permits tipping as of the closure under the action of the pressure medium about the spindle situated on the opposite side of the closure. However when the regulating spindle is turned, in the first phase it turns in relation to the closure and restores the closure from a tipped position to-wards a position where both spindles are at right angles to the longitudinal axis of the valve flow passage.  On further turning of the regulating spindle in the same direction the torque required for turning the closure to desired position is low.

Abstract: ABSTRACT    A diesel engine monitor monitors the exhaust gas temperature of each cylinder in a diesel engine.  A thermo-couple is coupled to each cylinder in the engine and the monitor scans the analog signal output from each thermocouple which is proportional to the engine exhaust temperature of the cylinder.  The analog temperature signal is digitized in an analog to digital converter and stored.  A microcomputer controls the operation of the monitor and reads each individual temperature after it has been stored.  The microcomputer numerically averages the last temperature stored from each cylinder to form a total moving average for the engine which moves as each engine cylinder exhaust temperature is rescanned The monitor first checks to see if the temperature signal from a cylinder is due to an open thermocouple.  The microcomputer then compares the latest temperature to the previous temperature for that cylinder to determine if it has changed more than 100 degrees.  The temperature is then checked against a preset high limit temperature, then 90 percent of the high limit or a prewarn condition, then the low limit, then 110 percent of the low limit or prewarn and then checks the temperature against an allowable deviation from the total moving average of all the cylinders.  The monitor eliminates any open thermocouple readings from the cylinder average computation   The monitor has an adjustable setting for the high, low and deviation set points.  The monitor will generate an alarm if the temperature fails any of the tests except for the 100 degrees difference check which is merely used as a noise checker.  The monitor will recheck when any limit has been exceeded and will await a predetermined number of scan cycles for alarming for that condition.  An audio or visual alarm may be operated and/or sent to an external alarm.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure is directed to an apparatus and method for determining the water-filled porosity of formations surrounding a borehole by means of an electromagnetic propagation tool.  In accordance with one embodiment, a transmitter emits microwave electromagnetic energy into a borehole which is received by two spaced apart receivers within the borehole.  The received signals are utilized to obtain the attenuation and the relative phase shift of the microwave electromagnetic energy propagating between the spaced locations.  The conductivity of the water in the formations surrounding the spaced locations is determined, for example, from the conductivity of the drilling mud being utilized and the nature of the mud filtrate resulting from invasion of the formations by the drilling mud.  An indication of the water-filled porosity, ?w? of the formations adjacent the region of the spaced locations in the borehole is provided by a quantity which is directly proportional to the product of the attenuation and phase shift quantities and inversely proportional to the conductivity of the formation water.

Abstract: 1950-77a ABSTRACT OF THE DISCLOSURE             Developing apparatus for latent images of X-rayed objects on dielectric receptor sheets wherein two identical sheet carriers each of which constitutes a segment of a cylinder and extends along an arc of less than 180 degrees rotate with and relative to each other about a horizontal shaft.  The peripheral surfaces of the carriers have suction ports which attract receptor sheets during travel of carriers from a starting position, past several corona discharge devices, a developing unit which can be operated to contact the latent images with a liquid developer, and a fixing unit for developed images, on to a sheet evacuating station.  A roller on an arm which is rotatable on the shaft serves to drape a freshly delivered sheet onto the peripheral surface of that carrier which is held in the starting position.  Discrete motors are provided for the arm and for each of the carriers. The combined length of the corona discharge devices or of the developing and fixing units, as considered in the circumferential direction of the cylinder, is less than the difference, between the combined length of the peripheral surfaces of the carriers and the circumferential length of the cylinder.  This renders it possible to complete the treatment of the receptor sheet on one of the carriers while the other carrier dwells in the starting position.  The corona discharge devices are operative when the developing and fixing units are idle, and vice versa.
